IMPROVEMENT IN MACHINES FOR MAKING SHOE-NAILS.

Specification forming part of Letters Patent No- 159,S52, dated February16, 1875; application filed August 7, 1874.

To all whom it may concern:

Be it known that I, LEANDER SoULE, of Taunton, in the county of Bristoland State of Massachusetts, have invented a new and Improved Machine forMaking Shoe and Dowel Nails, of which the following is a full, clear,and exact description, reference being had to the accompanying drawings,making part of this specification, in which Figure 1 is a perspectiveview of my improved machine. Fig. 2 is a transverse vertical sectionthrough the same. Fig. 3 is a horizontal section through a portion ofthe same, taken in a plane passing through the center of the dies. Fig.4. is a vertical section on the line 00 a: of Fig. 2.

My invention relates to a machine for making nails, such as are used forsecuring heels to boots and shoes, and also as dowel-pins, each nailbeing provided with a collar; and my invention consists in thecombination of a pair of auxiliary dies with the main dies of anail-1nachine, a space being left between the main and auxiliary dies,so that as the blank is griped a collar will be formed by the spreadingof the metal into the space so left, this space being afterwardcontracted by forcing one pair of dies laterally toward the other pair,so as to reduce the thickness and increase the diameter of the collar togive it the required form.

To enable others skilled in the art to understand and use my invention,I will proceed to describe the manner in which I have carried it out.

In the said drawings, A represents the bed of the machine, to which ispivoted, at a a, the gripin g-lever B, which is advanced against theresistance of a spring, I), by a cam, O, on the driving-shaft D, whichruns in bearings in standards d, rising from the bed A. e f are the maindies, the movable one, 6, being secured in a groove, 5, in thegriping-lever B, and the stationary one, f, in a similar groove, 6, in ablock, g, rising from the bed A, the dies being held in place by clampsh. At the side of each of the main dies 6 f is placed a narrow auxiliarydie z, these dies t' being opposite eachother, and secured in andincrease its size the following device is em ployed E is a lever, oneend of which is attached to a rock-shaft, G, and to its other end ispivoted a connectingrod, l, the upper end of which is attached to acrank-pin, m, on a disk, H, secured to one end of the shaft D. Within agroove, 9, in the upper side of the lever E, is secured, by means of aclamp, a, a bar or compressor, 1), which, as the lever E is raised bythe connecting-rod l, is brought up against the auxiliary dies '5, andforces them in toward the main dies 6 f, thus contracting the width ofthe space k, which compresses the collar on the nail, reducing itsthickness and increasing its diameter, as desired, to give it the properform. This forward movement of the compressor 19 takes place as soon asthe nail has been griped between the dies, and on the withdrawal of thecompressor the spring of the auxiliary dies causes them to assume theiroriginal position, as seen in Fig. 1.

By adjusting the compressor 19 in its groove 9, the amount of lateralmovement of the dies i may be varied, and the thickness of the collarcorrespondingly changed.

The collar 8 may be formed at any desired point between the ends of thenail by varying the relative width of the main and auxiliary dies.

The shears for cutting the blank from the plate, and the feedingmechanism for delivering the blank to the dies, forming no part of myinvention, are not shown or described.

What I claim as my invention, and desire to secure by Letters Patent,is-

1. The auxiliary spring-diest i, diverging from and in combination withthe main dies 0 f, and constructed substantially as and for the purposedescribed.

2. In combination with the dies 6 f i i, having a space between them,the compressor 19, for forcing one pair of dies laterally toward theother pair while the nail is griped between them, substantially as andfor the purpose set forth.

Witness my hand this 29th day of July, A.

LEANDER SOULE.
